ABSTRACT
Meningiomas are among the most common primary benign tumors and most of them are primary intradural lesions located in the subdural space. According to Casas-Perera et al., they represent 36.4% of the primary intracranial tumors. Meningiomas may be incidental, small, and slow growing tumors or extensive and/or rapidly progressive growing masses. There is a subset of meningiomas that arise outside the intradural space, called Primary Extradural Meningiomas (PEM) which, as the name suggest, develop outside the intracranial compartment and in this myriad of locations, Primary Intraosseous Meningiomas (PIOMs) are considered an uncommon type of PEMs that constitute up to 2% of meningiomas overall.
It is important to highlight the fact that PIOMs, in a different fashion as intradural meningiomas manifest, present themselves with a variable radiological appearance and clinical behavior as classical intradural meningiomas do. The treatment usually consist of complete en-bloc resection, and as straightforward as may seem at first glance, this goal may be challenging particularly due to the lack of clear tumor margins on conventional imaging studies .
The lack of a clear and standardized definition of this family of tumors remain within the domain of confusion. This is even more patent in the pediatric population, where except for very few report cases and specialized literature most of them fail to mention even an incidence or frequency in pediatric patients.
We present a case study of a 15-year-old male patient that suffered of refractory to anti-epileptic drugs (AED) seizures in order to attempt a resection.
